Thanks. Looks like I hadn't missed any manufacturers out there -- darn. Was hoping I'd just overlooked someone. I'll look at my DIY options. The best might actually be something along the lines of sash/vest garters, to attach the bottom of the sash to my shorts -- or snap onto a jersey. Or I might end up making the whole kit try to ride up instead of just the reflective gear. RUSA doesn't allow it to be part of your jersey -- it has to be a vest or sash, or I'd just sew/tape onto one that fits already.
